Cool! We're actually in the process of overhauling consoles for VM Portal.
We currently have Windows RDP in the Admin Portal, and we are actively
working on it for VM Portal. Here are some screens from the design:
[image: image.png]
[image: Selection_375.png]
[Kudos to our awesome designer, Laura Wright]
We also have SPICE (thick client) fully implemented in both portals, thick
client VNC in both portals, novnc (web-based) in Admin, and novnc coming
very soon in VM Portal (4.3.2 at the latest, but I hope 4.3.1) as part of
the overhaul.
Is Mechdyne TGX much different than Windows RDP, SPICE, and VNC? If so,
what is the use case for using that over Windows RDP / SPICE / VNC?
Also, would you mind please reviewing the designs we have so far? I'm
interested in others' opinions, especially someone who has already been
thinking about this.
Console design doc (start at page 41 ish):
https://docs.google.com/document/d/1m-pM0VVgeZmVCJFs2lLuzC9KUVV-X1cDfLXPb...
And I would certainly love for you to help test it out as we're nearing
completion, at the least. If you want to code, we would love to have you :)

Silent errors in storage code on Vdsm startup
by Milan Zamazal
Hi, I'm trying to run Vdsm with Python 3, which exposes various Python 3
incompatibilities in Vdsm code. I'm currently semi-stuck on Vdsm
crashing very shortly after startup with:
Panic: Error initializing IRS
Traceback (most recent call last):
File "/usr/lib/python3.6/site-packages/vdsm/vdsmd.py", line 95, in serve_clients
irs = Dispatcher(HSM())
File "/usr/lib/python3.6/site-packages/vdsm/storage/dispatcher.py", line 46, in __init__
self._exposeFunctions(obj)
File "/usr/lib/python3.6/site-packages/vdsm/storage/dispatcher.py", line 56, in _exposeFunctions
if hasattr(funcObj, _EXPORTED_ATTRIBUTE) and callable(funcObj):
File "/usr/lib/python3.6/site-packages/vdsm/storage/sp.py", line 85, in __getattr__
raise se.StoragePoolNotConnected
vdsm.storage.exception.StoragePoolNotConnected: Storage pool not connected: ()
That wouldn't be a problem by itself, errors are expected in Python 3
experiments. However the problem is that this is often the *only* error
I receive.
I've found out that HSM() call spawns threads, which apparently don't
have chance to report their errors before the panic above kills Vdsm.
For instance, there was a string-byte mismatch in running iscsiadm
scanning commands. Only after I added time.sleep to the end of
HSM.__init__, I got an error + traceback from that and could see what's
wrong. That worries me a bit, because it might mean that if some
initialization external commands are not fast enough, Vdsm may not be
able to start.
After fixing some problems, I get the panic again, even with the sleep
at the end of HSM.__init__, and again without any other error. It's
difficult to proceed in such a situation -- any tips what to look at or
to look for are welcome.
FWIW, my vdsm.log now ends with

Plans for ovirt-guest-agent
by Sandro Bonazzola
Hi,
I understood that most of the ovirt-guest-agent logic moved to
qemu-guest-agent.
We are currently shipping ovirt-guest-agent for Fedora, EL7 and Windows,
all of them using Python 2.
Most of the bugs around ovirt-guest-agent have been closed wontfix or
deferred with comments like "The guest agent is going away in 4.3 in favor
of the qemu guest agent, so this will not be resolved" but we still have
the ovirt guest agent around in oVirt 4.3.0.
What's the plan for 4.3 updates and 4.4? Is it safe to not install
ovirt-guest-agent but just qemu-guest-agent? Wich version of
qemu-guest-agent is required to completely replace ovirt-guest-agent?
Thanks,

Proposing Yedidyah Bar David (didi) as a integration maintainer for oVirt Engine
by Sandro Bonazzola
Hi,
Didi is maintaining OTOPI and wrote with me most of the code in
engine-setup back into oVirt 3.3 release. He maintained that code across
the following releases along with the backup and restore tool and the
rename tool. He's the most active contributor within integration team for
ovirt-engine related code.
I would like to propose Didi as integration maintainer for oVirt Engine.
Thanks,

propose Ravi Nori as a frontend maintainer for ovirt-engine infra
by Greg Sheremeta
Hi all,
I'd like to propose Ravi Nori as a frontend maintainer for ovirt-engine
infra team. While the infra team typically hasn't had a frontend
maintainer, Ravi has strong knowledge of all of the frontend infra pieces,
including everything related to SSO, welcome page, and GWT in admin portal.
Best wishes,
Greg
